For more information, see NTFS Health and Chkdsk. When NTFS is used with Cluster Shared Volumes, no downtime is required. For larger corruption issues, the Chkdsk utility, in Windows Server 2012 and later, scans and analyzes the drive while the volume is online, limiting time offline to the time required to restore data consistency on the volume. NTFS continuously monitors and corrects transient corruption issues in the background without taking the volume offline (this feature is known as self-healing NTFS, introduced in Windows Server 2008). For example, after a server crash, NTFS can recover data by replaying its log files. After a bad-sector error, NTFS dynamically remaps the cluster that contains the bad sector, allocates a new cluster for the data, marks the original cluster as bad, and no longer uses the old cluster. NTFS uses its log file and checkpoint information to restore the consistency of the file system when the computer is restarted after a system failure. To learn about the newer Resilient File System (ReFS), see Resilient File System (ReFS) overview.
